Two thousand square feet of warm.

The largest Q — a tall near-square window, 38,000 BTU, and the “Adjustable Rear Vent” that eases old-house installs.

The big window

26 by 24¼ inches of glass — the Q family’s largest view of the fire, still a perfectly clean face.

A real heater

38,000 BTU and a “150 CFM Room Fan” — the maker rates it for 2,000 square feet.

Made to retrofit

“Adjustable Rear Vent” in Enviro’s words — the vent meets the wall where the old one left it.

Quick answers

The three things everyone asks.

Do I need a chimney?

No. The Q3 is direct vent — a 4″ intake and 6⅝″ exhaust run out a wall or up through the roof. No masonry, no liner, no sweeping.

Can it replace my old gas fireplace?

Often, yes — the “Adjustable Rear Vent” exists for exactly that. Send a photo of what you have and we’ll tell you straight.

What’s the upkeep?

No wood to haul, no ash to sweep. Like any gas fireplace it wants an annual service — that’s our trade, and the crew that installs it does it.

What it costs

Priced to your home — not from a chart.

Every wall is different — framing, venting, gas line — so your price is real, not a guess.
